I wrote this post for my personal blog, but I thought a few people might get a kick out of it here. It's hard to believe it's been 10 years! Read on for my fuzzy recollections.

My apologies to anyone in the past two months who tried to download my sample Excel spreadsheet that went along with the article " VBA and Excel for Engineers and Scientists – Part 2". I didn't notice that there was a problem with the download until a new member emailed me about it (thanks Chris). I believe that it's working now, if not be sure to email me! By the way, I've been out in the field since last week, sorry for the sparse posts.

Announcing a new sister site to GeoPrac, - a geotechnical search engine! This search engine is powered by Google's Custom Search with it's own clean interface. Search queries only return results from sites that are hand picked by myself and other members of So you don't have to sift through results that aren't relevant to geotechnical engineering, geological engineering and related disciplines. Screenshot 

The source of sites included in the GeotechSearch search engine come from the GeoLinks section of this site. Any member can contribute links (subject to approval) and they will then be included in the search engine results within a few days. So if you're not a member, why not join And then contribute a link to the GeoLinks section. I'm incredibly excited to really start tapping into the capabilities of GeoPrac as a true online COMMUNITY of "geo" practitioners for the benefit of all in our profession...the possibilities are endless!

I'm a little behind with this one, regular readers might know why, but here are the top content items of the first three months of 2008 (as of 4/3/08 actually). They are in order of normalized hits (number of page impressions per day) with the total number of page impressions listed in parenthesis. There were a few near the top of the list that I was a little surprised to see and you might notice some funny math, but I didn't bother to hand edit things. Click through for the whole list.

GeoPrac Turns One! PDF Print E-mail

I can hardly believe it, but today marks the one year anniversary of the launch of GeoPrac! It has been a good ride so far, things haven't exactly gone quite like I planned, but when has that ever happened? I'm grateful to all of the visitors who frequent the site and particularly to the people who have contributed an article or geonews item. I intend to do a wrapup of the most popular articles/news items of Q1 2008 and a "state of the union" type post with some thoughts about where I intend to take the site in the coming year. But I've just been out of gas with the newborn in the house. I'll try to get to it this weekend.

Here's to a good first year and many more to come! Cheers!

Regular readers of GeoPrac are probably used to the sporadic nature of my blogging. Sometimes I add entries a couple times a week, sometimes once a week. But I wanted everyone to know why I haven't posted in a while and why it may be kind of sporadic for the next few weeks as well.

My second daughter, Michaela (Makayla), was born on Thursday, March 13. I've been enjoying time at home with my family, helping my wife get adjusted to the prospect of two kids around the house! Thanks for your patience. I'm hoping that by next week's 1-year anniversary of I'll have a chance to write about "the state of the union" so to speak and talk a little about my goals for the site in the coming year. Thanks to all you loyal readers for sticking with me! -- Randy (rockman)

Problems with Registration and Outside News and Blogs PDF Print E-mail
Written by Randy Post   
Tuesday, 22 January 2008 06:52

I just found out that there was a problem with the site that prevented new members from registering on GeoPrac. My appologies to anyone who got a permission error after filling out the registration form. I humbly invite you to try again at your convenience.

Additionally, the Outside News and Blogs page that I was patting myself on the back for has apparently not been visible to the public either. Great big oops on my end. It should be up and running now.

Thank you to Elizabeth at the ASCE Geo-Institute who took the time to let me know about both problems. Do me a favor and check out the new G-I News Feed blog that she maintains.

Personal Reflections on I-35 Bridge Collapse in Minneapolis PDF Print E-mail
Written by Randy Post   
Wednesday, 16 January 2008 18:25

On January 15, the National Transportation Safety Board released a safety recommendation letter report to the FHWA related to the I-35W bridge collapse in Minneapolis Minnesota that claimed the lives of 13 people and injured 145. The safety recommendations are based on the findings of an interim report from the FHWA Turner-Fairbank Highway Research Center  that some gusset plates, components of the steel trusses, were undersized (not thick enough). This deficiency was confirmed to be a flaw in the design and not construction-related based on review of the original drawings from the 1960s and inspection of the wreckage. Whether this was a calculation error or a drafting error will perhaps never be known as only portions of the original design calculations were located. But the point is that it was never caught by any reviewers.

When this event first happened back on August 1, I remember being very shaken up by it. After my initial sadness for the victims of the accident, my first thought as a geotechnical engineer was: “were the foundations at fault.” As more information came out, it quickly became evident that the failure did not have anything to do with the foundations but that it was related to the superstructure of the bridge. But this still was something that profoundly affected me. (Continues…)
